To all whom it mayconcern: i

Be it known that I, GEORGE H. HoLoATE, a. citizen of the United States, residing at Philadolphin, county of Philadelphia, and State of Pennsylvania, have invented o certain new and useful Improvement in Carbureters, of which the following is a specilication. My invention relates to a new and useui improvement in cnrbureters, the suine being especially designed for use in connection with portable lumps, although I do not confine myself to this particular adaptation of' the invention,l because I may employ the improved device or parts thereof in any kind of apparatus and for different purposes.

, One object of this invention is the provi-- sion of an exccedin ly com act carbureter which may-be cmboxied in t e construction of a lmnp or it maybe used as a font. for standard-size lamps, thus enabling the device to be employed interchangeably in connection with an kind of u lmnp-body of o. eertain size on permitting;r u merchunt io snpply the public with u font swuilohle for service 1n lamp-bodies owned by the purchaser.

A furtherobject of the invention is to equip the structure with means for automatically inducin the circulation of en oir-current adopt to bc cher ed with u hydrocarbon and produce a comlriustible vapor available for heating un incandescent nuintle.

Further objects in view nre the provisionI of means for cutting ofi' the circulation of nir and vapor by the simple nd'ustment of u sim gle device to prevent the leakage of vapor and to ullow the absorbent member of the carburetor to be recharged easily.

Further objects und advantages of the in vention will eppcur in the course of the suhjoined description, and the actual scope thereof will be defined by the annexed claims.

Reference being had to tin` accompanying drawin forming n port of this s ierilieatios, in whiclilsimilur characters of rellerence indicete corresponding ports in all the Figures, Figure 1 is nlongitudinal verticul section through my irnproved carburetor shown' in form of a lomp3. Fig. 2, a horizontal section taken on the lino'2 2 of Fig. 1; FigJ n. horizontal section taken on the lino 3 3 oi Fig. l; Fig. 4, an cnlor ed horizontal section taken on the lino '111111 Fig. l' Fig. 5, n. detail view of the lower portion of the font, showing a modified means for closin the Viower und whentho font is filled wit the vapor-producing fluid.

In the drawings, A re )resents the font or receptacle in which the n sorlwni member is contained. This font is cup-shaped. with :i depression A' in the center ol' 1hr bottoni thereof.

B represents the absorbent onderh-rl row tained within the font A, und ihis absorbent. materiel muy he either u rmnpositon ofplns-r wreef-po.risV or ilw like, telt, sponge. ornnv other materiaal rnpuhle ol' absorbing u liquid: hut I prefer to use ovomposiiion ol' plaster-oi"- perisond otheringredients wliivh inuylw divided intoseriionssnd heldnithin the font ,so that there. are spurl-s between the sections lo uliowforthe freccirrulut ion of oir.` This muy be accomplished in my manner desired. iluL forni shown in the drawings,however.lnng preferable, which consists ol concentric rings nested one inside ille other with spores; hetween thc rings. In order to provide .fr free nir und vapor space above und below the nhsorbent mnteriahlf secure. upon the inside nl' the font the perforiited screen (i, :i nein dis tence shove the bottoni oi' the foul noon which the nbsorhcnt material resis, rnd rho absorbent material does not rencia quilc to the top of the font, and if desired :L perform ed screen C* muy he placed shove the absorbent materiel to'hold said materiel in place. Thus it will be seen that. un upper chamber@ is formed und also n lower ehmnhor G. ,Y

D forms the top of the. font, whiohin'uv be preferably threaded around the outside oi' the. sume., und st the renter ci the top e tube D extends downward and is threaded imo the depression A' at the bottoni of the fontA The lower end of this tube l)is closed, exi-opt us for airinlets, to be hereinafter described; hut scid tuhe D is open nt the top, und within this tube D is fitted a tulw l1), 'whieh is open at the top, but closed nt the bottoni, exi-cgt for eert-sin frir-inlets- Fit ted within the lu c E is o third tube l*`,whieh isulso closed :it the lower end und 'lits clos-el on lop of the lower end of the tube E,os the ower end ci' the Luhe E fits upon thc top of. the lower und of the tube D. Theupper end of the ruhr as cxtends upward above the font, und where the eurbureter is to he used as n hun i n mantle G is sus nded over the upper ond ,f the lube; F, un s chimney Il surrounds the m'nntlc in the woll-known manner.

The tubvs'F and D uro stutionnry tubes,

und any means can be employed `for innking the central tube stationary, here shown es by means of n square bolt passing through from the bottom ofthe tube D to the bottom of the tube F, the bottom of the tube E having an opening large enou h so that the tube E can revolve in between t e tubes F and D.

Through the to D of the font are provided openings J, through which air may enter, and assingdownward through the spaces of the a sorbent material, which is saturated with the vaporproducing fluid, becomes heavier byy the h drocarbon and flows into the lower cham er C3. Openin s K are formed through the walls of the tu es F and D coincident with one another opposite the space C, and throu the revolving tube E are formed openings which ma i be brought in register with the o enin s K y revolving said tube E. Thus w en t e o. enings L are fin re ister with the openings K t.ie gas formed by te mixture of h drocarbon and air will Apass upward throughr the central tube F if ang' heat is applied at the up ier end of the tu e to cause an induction. nthe case of a lamp this induction is generated b i heat being applied within the chamber and the gas passing u the tube F'is lighted almost mstantl an the burning ofthis gas tur-- nishes t e heat for keeping ii the continuous induction. The openings are closed t i' o ened simultaneously with the opening of t e passages K. To accomplish this, I provide a ring M, which is connected by springarms M with the middle or revolving tube i. This rin M comes down upon the top of the font witl a spring-pressure over the openings J and said ring is provided with openings It 2, which may be brou ht in and out of register with the o enings Thus as soon as the o enings are opened for admitting gas to t e inner tube F the openings J and Ml will be brought in register with one another to admitair, and the proper mixture can be obtained by revolvin the tube a more or lessdistance. A hand e M3 is rovided for the revolving of the ring M, w iich in turn revolves the tube E. It is desirable to also admit the outside air at the lower end of the tube which carries the gas upward; but this lss air is only to be admitted when the mixtun` is very rich and when the fluid is nearly evaporated from the absorbent material and it is necessary to open the ports J and K to their widest extent. Then no air, or at least ver little, should be admitted to the lower endy of the gas-tube. 'Io accomplish the ad mission of this air and the proper regulation of the same from the one point, I form through the bottom of the tubes F and D the orts N, which are c incident with one anoti) Ewhich revolves between the bottoms of the tubes F and D', I form the openings which may be brought in and out of register with the ports N; but these o enings O are so located that they will only e in re rister to their fullest extent with the ports N ywhen theports ier, and through the bottom of the tube J and K are closed, and as the iorts Juud K are gradually opened the ports will be gradually closed, so that when said ports J and K are fully opened the ports N will be fully closed. Thus it will be seen that the regulation of the three inlets will all be aecomplished from oml handle or lever, and the nir will be admitted at the upper end of the fonl directly above the abs( i'bent material and at different oints around the surface, so that the air wih'be equally distributed as it entersy P represents the body of a lamp, which may be of any suitable shape or design, the font simply resting within the body and may be easily removed bv lifting upward.

When it is desired to charge the absorbent material with the gzisolene, benzin, naphtha, petrol, or other iluid hydrocarbon, the top D is unscrewed from the font, which also removes the tubes D',l E, and F, trgether with all the parts attached thereto. simply the font open at the upper end, and the fluid is cured into the font, and when the niateriar will absorb no more fluid the residue is drained out. As the lower end of the fi nt must be opened for the admission of air to the central tube F, some means must be employed for closing the lower end of thefont when the same is to be filled. In Fig. l of the drawings I have shown means for automatically dlcsing the lower end oi' the font when the font is removed from the lampbody and automatically opening the saine when it is placed in the lamp-body. This consists of aplug-vnlve Q,located in thelower end ofthe de ressed portion A' of the bottom of the font. is an opeiiin f formed throu h the bottom of this depressedlportion, and t ie valve Q is adapted to be pressed downward and close this o ening by means of the spring Q2; but when tie font is placed within thtl lamp-body a stem Q4, extending downward from the valve, strikes against a cross-piece P on the lamp-body, which holds the valve open for the admission of air as long as the font is in the body; but as soon as the font is removed for filling the valve automatically closes. After the font has been illed and it is desired to iour otl` the unabsorbent liquid if desired the liquid can he drained off through the opening Q by simply raising tlul valve Q. This might be more convenient than pouring it out of the font by tilting the This leavesA IOO same, espociallyif such absorbentmaterial is used which might be disarranged by the tilting of the font. (lf course the lower end of the font could be closed otherwise than automatirallyas, for instance, b v means of a scrmv-eap It, as shown in Fig. 5, this rap lt being removed when the font is in use and being screwed upon the nipple A when the font is to be filled. l i

It will thus be seen by this improved construction of carburetor that I am enabled to control all of the inlctopcnings from one lever Vwithout revolving the eenral tube throuv'h which the gas passes, and by having the iiilet for air directly throuuh the top of the font a better distribution o the air is.aecoiuplished, and b v means ofthe spriiigring a gastight joint is maintained at all times, and by providing for tue opening of the entire top of the font access can be gained to the absorbent material at all times without doin any unsoldering.

t) :ourse I do not wish to be limited to the exact construction here shown, as slight modifications could be made without departin r from the spirit of the invention.
